Abstract:
HYPOINVERSE2000 determines earthquake locations and magnitudes from seismic network data like first-arrival P and S arrival times, amplitudes and coda durations. The present version HYPOINVERSE2000 is in routine use by the Hawaiian Volcano Observatory, The Northern California Seismic Network, the Nevada network, and many other networks. It is the standard location program supplied with the Earthworm seismic acquisition and processing system and has thus gotten wide use. Crustal models can be multiple to cover different regions, and either flat layer or flat layer with linear velocity gradients.
